drm/i915: Don't clflush before release phys object
When we teardown the backing storage for the phys object, we copy from the coherent contiguous block back to the shmemfs object, clflushing as we go. Trying to clflush the invalid sg beforehand just oops and would be redundant (due to it already being coherent, and clflushed afterwards).
